To all whom it'may concern:

Be it known that I, JOHN M. DALY, a citizen of the United 'States, residing'at Chicago, the count Y of-Gook and State of llinol's, have invented certain new and useful Improvements in Computing-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the "invention, which will enable others skilled in the art to which and use the same.

This invention has reference to acomputit appertains to make ing machine and relates particularly to a:

gross tons of cars and contents into pounds of draw-bar pull, and for automatically adding and displaying on said register-the total One of the objects which I have in View in reducing grosstons of cars and contents into pounds of draw-bar, is-to compute and cats an amount at variance to and'difierent from that called for by the number equal to the gross tons of cars and contents aptents will be automatically increased at predetermined intervals, "thereby causing said machine-to compute and register for the different amount, said allowance to be made depending on the location of said car and contents in a train. The results to be obtained by the present evice is in some respects similar to that aimed at in machines upon which patents have already been granted to me and by others upon which'applications for patent are now pending. The. patents referred to are numbered 715,197, 715,199 and 715,201, dated 'Dec; 2', 1902; also Patents Nos. 939,221,

Expert mechanical -men have devised certain formula for arriving at the total! weight of car and contents an engine should haul, by both practical and dynamometer car tests as follows ;Take the weight of engine on drivers, the size of cylinder, the size of dr ver wheels, the steam pressure,

and by mathematics determine about what its tractive power in pounds is on To determine the gross tons an engine can haul over certain grades and curves another formula has been adopted as follows:- For each degree of curve, allow one-half pound of draw bar pull, and foreach'foot of grade to 't-he mile allow .386 pounds of draw-bar pull. For example, take an engine and place a dynamometer car next to the tender, then couple one hundred and fifty (150) cars of forty (40) .gross tons each behind the dynamomete-r car and engine uses its maximum power to move the train on a level exerting and recording on dynamometer chart twenty thousand (20,000) pounds, which indicates its tractive power. Twenty thousand (20,000) pounds divided by one hundred fifty (150) cars equals one hundred thirty-three (133) pounds per forty (e0) ton car; one hundred tlIIItY'thICB (133) pounds divided by forty (40) tons equals three (3) pounds per ton draw-bar pull on level. Now on a thirty (30) foot grade having a four l) degree curve we must add one-half pound, per degree of curve equal to two. (2) pounds for four degree curve, on grades .386 for each foot of-rise thirty (30) by .386 equaling eleven and one half pounds (111;). )Nheel friction at three (3-) pounds, curve at two (2) pounds and grade at eleven and one half (11%) pounds, equaling sixteen and one half (16%) pounds, hence, an engine can haul over this grade in forty (40) ton cars twenty thousand (20,000) pounds. Twenty thousand (20,000) pounds divided by sixteen and one half (163 equals twelve hundred and twelve (1212) pounds.

The pounds of draw-bar, pull per ton of gross weight of car will vary according to the gross weight of each car. For example, on

the numbering wheel shown at in order a level.

a level a ten (10) ton car has seven (7 pounds per.ton, a total of seventy pounds; a forty (40) ton car has three (3) pounds per ton, a total of one hundred and twenty (120) pounds and a seventy (70) ton car has two pounds per ton, making a total of one hundred and forty (140) pounds. Hence, an engine with twenty 'thousand (20,000) pounds tractive power can haul two hundred and eighty five (285) ten (10)'ton cars, equal to 2850 gross tons; on forty (40) ton cars an engine can haul one hundred and sixty six (166) cars of one hundred and twenty (120) pounds each which is equal to 6640 gross tons; and on seventy (70) gross ton cars an engine can haul one hundred and forty three (1 13) cars of one hundred and forty (14.0) pounds each, equal to 10010 tons. In each instance the draw-bar pull on the engine is twenty thousand (20,000) pounds. This applies only to a level, any curve or grade creates additional draw-bar pull per ton and reduces the gross tons to be hauled.

It being the custom toha'ul ten and fifteen ton cars in trains together with seventy (70) ton cars, and by reason of this large varia- "'on in the resistance per ton in draw-bar I l of each weight of car, an intelligent ad ustment must be provided. Printed charts can be distributed and placed in the hands of switchmen, yardmasters, conductors, and others whose duty it is ,to see that engines are properly loaded, but they must use the way-bill or manifest that accompanies the car showing the gross weight of each car and contents in connection with such chart or scale. For example, in building up a train if the first car is ten tons, they enter the ten tons on report opposite the car number, then refer to the chart, and find its draw-bar pull over the grade and curve'to be equal to eleven pounds per "ton; the next car it a forty (40) ton car, is equal to two hundred and seventy (270) pounds and the next a seventy (70) ton car equal to four hundred and seven L07) pounds, they must continue to adjust each car until the'total draw-bar pullis equal to the rating, twenty thousand (20,000) pounds. If they do not stop when twenty thousand pounds is reached they must refigure or deduct the surplus, and as the average yardmaster, switchman or conductor is not. an expert in mathematics, and as they are required to take a check of their train from the cars out in the yard it is not practicable for them to always compute correctly the gross tons of car, to say nothing of adding correctly the total pounds of draw-bar pull, which is much more difiicult. T he pounds of draw-bar pull shown in the last instance, viz., a ten ton car equaling one hundred and ten pounds, a forty ton car, equaling two hundred and seventy pounds and a seventy ton carequaling four hundred and seven pounds, applies to avery light grade'of about eight (8) feet to the mile and a two degree curve, and for a train the average weight of cars being about forty (40) tons which would keep the length of trai'n down to a reasonable limit.-

7 If the average Weight of cars is twenty (20) tons each, then additional allowance must be made, this allowance I provide for as every ten (10) cars are added to the train,

all of which will be inore fully explained.

holes or ratchet teeth.

In order to provide'a device for quickly and accurately reducing from. gross tons to pounds of draw-bar pull, 1 have perfected a computing device that not only reduces gross tons to pounds of draw-bar pull, but also computes into one total the resistance in pounds of all carsin the train, and which automatically makes increased allowance per ton as the length of train increases or decreases by reason of large number of light or small number of heavy cars. It also registers the'total number of cars in the train when complete.

Hhe device referred to comprises a rectangular casing 'l which forms the side and end wallsadapted to have attached thereto the top 2 and bottom 3, all of which inclose the Working parts to be hereinafter more any described. The top 2 has the annular cut out'portions 4 and 5 and the slot (3 comit may be found convenient as well as prac ticable to provide the disk with more or less The disk 8 has a central depending tubular extension 12 forming a bearing for the diskon a stud-or spindle 13 jonrnaled in a vertically disposed bearing. 14, which passes through a longitudinal brace or frame part 15 disposed at short distance above the bottom 3 of the c 11g, see if l, and the disk 8 is located inkihe' casing below the annular opening 4-.

Covering the central portionoi tl disk 8 within the circle described by the U tions 9, is a. top'or cap plate 1S; wnicn 1S preferably connected with the upper end of the stud or spindle '13. The top plate-18 m separated from the upper face oi tl'iedi'sk' 8 by means of asuitable sized disk"'1'9 inte posed between the topfplate' and dist? so as to allow for the interposition of certainop erative parts which overlie andoperate above a portion of the top of the t isk S-and'f the perforations 9 therein as the disk is ro tated.

To the inner face of the flange 1.0 d'epending from the disk I pivotat inter- 313K 'vals the pawls 9,1, the free cnt "hich are adapted'to-be held p. jectin by means of the flat springs the under face of the disk-and :e 7, g u

said pawls- These pawls are ilpreterably spaced at every. twentiethtooth on the ratchet of the disk or beneath'the onehnn-x dredth mark indicatedhy 00, these pawls adapted to essively engage with each successive ratchet tooth of a 5 ratchet wheel 28'carriea on a longitudinally disp'osed shaft or red 24, one end or which is secured in the central bearing 1 4: and" the outer-,end thereott is secured in a vertical standard or bearingQfi, projecting upwardly from thepart d5, as seen in' Fig. l? ratchet wheel. 23-ihst referred to is r ably provided with ten ratchet" teeth and. the said ratchet :vvheel is'connectedwith j cated as 26 and. provided with numerals on its periphery, ranging from 0 to 9, Connected with or forming a part of the numbering wheel 26 just referred to is a disk or plate 2?, best seen in Figs. 3, it and 16 and this disk or plate has pivotally connected thereto a pawl 28, the free end of which. is held. upright by means of a spring 29 which partially encircles the disk or plate 27 and has one end secured thereto and the opposite end engaging the pawl, somewhat as seen in Fig. 16.

The pawl just referred to as being pivoted to the plate or disk 2'7 is adapted during each rotation of the numbering wheel 25' and the ratchet wheel to successively engage with a series of ratchet teeth 30 formedin the lower edge of the depending flange 31 of a disk 32. The disk is in most. respects similar to the disk referred to as 8, being provided .with the depending flange and ratchet teeth as specified, although the disk 32 is much smaller than the disk S, and like the disk 8 is provided with a series of perforations or holes 33 arranged in a circinnferential row disposed asuitable .dis

tanee inwardly from the edge of the said disk. It is preferable to provide the disk 32 with a series of fifty holes and a corresponding number of ratchet teeth, however, it may be found convenient as well as practicable, as was suggested in the use of the disk 8 to provide the disk 32 with more or less holes or ratchet teeth. The disk :32 is provided with a central opening and a tubular bearing adapted to be seated on the reduced upper extension 36 of the standard 25 heretofore referred to and extending through the standard 25 is a stud or spindle 37 which passes through the opening ll in the disk and is provided with a plunger 39 overlying an arm or pointer 39 which is adjustably carried on the upper outer end of the stud or spindle 3T beneath the plum ger 38 as shown in 2 and And ar ranged on the upper outer face of the disk 32 I have arranged a series of characters, preferably numerals as shown from O to 49 and these numerals are disposed between the outer edge of the said disks and the holes or perforations 33 therein, so that as the disk is rotated through the engagement. of the pawl 28 on the plate 27 with the ratchet teeth thereof, the numerals will pass beneath the slotted opening (3 for the purpose of coiiperaling with the numerals on the numbering wheel 2t? and the lllllllffl'ills' on the disk 8. whereby to properly register or indicate the pounds, of draw-lj ar pull as the disk 8 is operated for the purpose of actuating the said parts. The disk 2 is disiosed (,'(l'lllill. l'vxneath the annular open ing in the top 2 of the device R and prolfl'tlll partially across the upper face of disk and the path of the llllll'lQ l' 9 and perforations therein is a lug or stop 10 of the top of the casing 2, see Fig. l, and the said lug or step will be engaged by the arm or pointer 39, referred to as being carried on the upper end of the stud or spindle 3'7. T he arm. or pointer 39 extends radially from the center of the disk and has its outer end disposed so as to describe a circle about the eircuinferential row of numerals arranged on the upper face thereof, as seen in Figs. 1, 2 and 9, and extending up from the said arm or pointer and its opposite sides is shown a pair of cars 41 to which and between which. is pivotally connected a linger 1-2, the rear end of which is adapted to be normally held in a raised position, as seen in Fig. 9, by means of the'spring seated in a tubular opening 4A in the extreme upper end of the stud or spindle 37. Raising the rear end of the finger 'l2 positionsthe forward end thereof in contact with and above the outer end of the arm or plunger 39 and said finger d2 has connected therewith a plunger L5 which passes through an opening in the outer end of the arm or plunger 39 and. is adapted to be inserted into a y one of the perforations or holes 33 the disk 32 as may be desired.

10 adjust and change the position of the arm or plunger 39 and the finger 4.2, the operator will press down upon the rear free end of the finger 6 .2 which will elevate or lift the front end thereof and in doing, will lift the plunger to out of the perforation or hole 33 in the disk 32 and adapt the arm or pointer 39 in the finger 42 to be adjusted on the upper face of the disk. The plunger projects down through the perforations 33 in the disk 32, as seen in Fig. 9, for a purpose to be described, and when raising the plunger by depressing the finger, the movement of the plunger while it is such as to release it from the perforations or holes in the disk, will not lift it out of the perforations in the arm or plunger 39.

l ieferrin'g again to the top or cap plate 18, the upper face of the same is provided witha boss lh through which is carried and adapted to have movement, an elongated pin 47 provided with a head 48 having a perforation t9. the head forming a shoulder which abuts with the inner edge of the boss 46 as shown in Fig 1 and 2. The pin l-T overlies and ero s the outer edge of the plate 18. the cn'cumfin'ential groove 20 formed between the outer edge of the plate 19 and the inner edge of the band 16 and partially crossing the band l is adapted to be inserted into any one of a series of perforations indicated as 50 whirh are formed in the concave face of an oil set 5l. of the top of the casing. best seen in Figs. 1 and T. The pin l? is adapted to be held pro- ;rcted forwardlv to prevent the same from heing accidentally iiliscngaged from the pertli'c plate-l8 and "the said springfibears against a s'tuo oo 7 1 which prmects through a slotted opening urn depending from the'pin' 47 in thep'l'ate 18. An operator desiring to adjiist the position; ofthe pin 17, which also changes the position Of'lllG plate 18, inserts a pin orinctal pencil in, the perforation i9 in the head 48 of the pin 4?, draws the same toward the center of the plate 18' and releases the pin 47 from the perforation in the oil set 51, and then'oscillating the plate. lSso to bring the pin in frontof the 'pertoration .50 of the oil set 51- in which it is desired to insert the same, he releases the pin l7 and the spring 52 acting against the stud 53, as above described, will force the pin into its proper perforation and retain the same in that position until it is again desired to readjust the position of the in.

The devices just above describe act in conjunction with certain features of the device tobe more fully explained, for adjusting the same to engines of different ratings and the pin referred to as 47 serves as a stop member against which a finger or metal needle engages when the same has been inserted into a hole or perforation 9 of the disk 8 for partially rotating the same in computing gross tons of cars and contents.

and reducing the same into pounds of drawbar pull, all of which will be more fully explained.

I will now proceed to describe the devices in connection with the disk 8, the disk 32, and the numbering wheel 26, whereby they may be simultaneously and automatically returned totheir normal or initial positions, which will place all of the parts mentioned at 4G 0' v I Encircling the depending hub or tubular bearing 12 of the disk 8 is shown a. cpllar 5eloosely carried thereon, the hub or bearing of the disk-provided with a lower flange 55, see Fig. 4%, which retains the collar 54 in working position thereon. To this collar is connected one end of a fiat coil spring 56, the opposite end of which is secured, to the under face of the disk 8 and for retaining t-he said spring in working position, I have provided the disk or plate' 57 which is secured to the collar 54 between which and the under face of the disk 8 the spring 56 is located. Pivotally connected to a pair of ears-58 .on the upper face-of the collar 54 is shown a small pawl 59 which depends alongside of the said collar and the free end of the said pawl is held against the lower portion of the hub or "bearing IQ of the disk '8 and the upper end of the bearing 14- above described, by means. or the spring 6621s shown in Fig. 4-; it" is adapted that the pawl 59 shall engage successively a series of latery projecting pins 61 seemed t t p end of the -bearing 14, there being pre l ably (5) fiv'e pins and in the 0peI'al'iiOD".Q"-' the disk '8 itis intended tojwind up the spring 56 'sufiiciently to return the said to 06 whenever it is desired-.1 Todo this,

I provide the lower flange of the or bearinglQ of the. disk 8 witha campo'r tion 6:2, which, after one-fifth rotation' of the disk 8 the cam portion 62 will engage with a beveled 'face 63 of the pawl 59,-and

swinging it outwardly will cause it to be disengaged from the pin 61 with which it engages and allow the spring 56 'to relax, which will permit the collar 54: to advance the distance between the pin with which it was engaging and the preceding pin. The

spring 60 upon the release of the pawl, forces i it again to the position shown in Fig. 4:, so

that it may be in posit-ion to abut with the preceding pin 61, andso thatv as the-disk 8 is again partially rotated it will again partially wind up the spring until the cam 62 referred to, again disengages the pawl from the pin 61 Thus, it will be'seen there is al-' ways suflicient tension on the'spring 56 to hold the disk and adapt it to be returned to its normal or initial position whenever it is so desired, and in a manner to be morev fully described. In Fig. 11, 'a detail View has been made showing the pawl '59 engaging a pin 61 and the disk 8being rotated, and

[winding up the spring 56;,in Fig. 12, being a View similar -to Fig. 1l, the disk 8 has r0;

tated into a position where the cam portion'62- has engaged, and has just about releasedthe 1 pawl 59 from the finger'61. Upon the release of th'e' pawl, it will be' seen that the spring will relax, forces the collar 54 forward, where the pawl 59 will engage with the preceding pin 61 and stop the collar. The disk 8'is held against any backward movement by means of a with .the ratchet teeth 11 on the flange 10 of the said disk. This pawl is'pivotally connected with a cradle 65 which iscarried on a rod 66. At five difl'erent points on the depending flange 110 of the disk 8, I have provided a ratchet tooth 11, with an extended tooth portion 67, seeFigs. 4- and 6. These extended tooth portions 67 are of such a length that whenthe cradle 65 is depressed, in a manner to be described, the

tensions 67 thus when the disk has been. moved and the spring 56 partially wound up, it will be seen upon depressing the cradle 65 and releasing the pawl 64 from the pawl 64. which engages ratchet teeth of the said disk,- the disk will return a predetermined distance or 'until' one of the toothextensions 67 engages with the end oft the pawl 64, which engagement will stop the movement of the disk at its normal or initial position, which is that position shown in Figs. 1 and 2. The pawl (ll is intended to be heavy at one end so as to cause the opposite end to be projected into the path of the ratchet teeth 1]..

Itwas previously explained that as the disk 8 was rotated the pawls 21 thereof would engage successively with the ratchet teeth of the wheel 23 for the purpose of imparting movement to the nrunbering wheel 20 carried on the shaft 24 and that with each rotation of the numbering wheel 26, movement would be imparted to the disk 32 through the engagement of the pawl 28 on the plate 27 with the ratchet teeth of said last mentioned disk. Means has been provided for holding t-he'ratchet wheel 23 and numbering wheel 26 to their work and in connection therewith means has also been provided whereby as the pawl 64: is released from the teeth of the disk 8 to permit it to return to its initial position, to also permit the numbering wheel 26 to return to its ini 'tial position. This means consists of a sleeve 68 which has a threaded engagement as shown in Fig. 4, with the stationary shaft 241; and on the sleeve 68 is provided a small stud or pin 69 which is adapted to be engaged by a stud or pin 70 project ng outwardly from the disk or plate 27. lVith this construction it will be seen that as the numbering wheel 26 and the disk or plate 27 are rotated, the stud or pin 70 engaging the stud or pin 69 will impart rotary movement to the sleeve 68 and it having a threaded engagement as shown, will be projected longitudinally thereon until the stud 5 5} disengages itself through such movement from the stud 70. The sleeve 68 is provided with a pair of annular flanges 71, which are spaced apart as shown forming a channel beta same in which is coileda lat spring attached at one end to the sleeve and the outer end to a tubular bar 73 best seen in Fig. 3. lVith the provision of this spring it will be seen that as the sleeve is rotated through action of the numbering wheel 26. it will. tend to coil up the spring and when the sleeve with its stud (39, is released from en the the stud 70, the relax of the sprin will cause the sleeve to rotate in the oppos l rcction and return it to i ts norn'ml or position, with the stud i9 abutting Wit stud 70.

There 'is provided a pawl 'T-ei which is fulcrumed to a support 75 secured to the brace 15.

The numbering wheel 103 is loose on the shaft 96 and is provided with a gear 104: adapted to be engaged by a pinion 10-5 on a stationary shaft or stud 106 which operated during each complete revolution of the numbering wheel 102' through and by means of a tooth 107, see Fig. 2, which intermittently ineshes with the pinion for imparting the proper movement to the numbering-wheel 103. The last mentioned numbering wheel is provided with an elongated hub portion 108 on the upper end of which is secured a cam 109 and secured to the said hub portion 108 is a flat coil spring 110, the outer end of which is coiled around the stationary shaft or stud 106.

When the numbering wheels are in their initial positions at 0, a pin indicated as lllcsecured tolthe numbering Wheel 1023 engages and rests upon a short vertical extension 112, projecting upwardly fronrthe' sta- Qtion'ary shaft 106, retaining the parts in position, but as the numberingwheels are rotated in the manner specified; the pin lllf'inoves away from y the "extension "112 v and Halso winds up the springi110, thus,

The car numbering devices which 'have just been referred to are in all respects similar to the car numbering devices, which have been shown and described in the last application filed-by me and bearing Serial Number 294,662.

In connection with the car numbering devices, I have provided an alarm' to indicate to the operator that a predetermined number of cars have been placed in the train, which it is understood to be the train length. This alarm consists of a bell 115 supported by the cross brace 83 and an arm indicated as 116, carried on the longitudinally disposed shaft 99 and having a knob 117 on its free end adapted to engage The means of op: erating the shaft 99 for the purpose of cansing the ringing of the bell 115 consists of an arm 118 carried by the said shaft which has pivotally attached thereto a pawl 119. In the rotation of the numbering wheel 103,

y when the'pin 111 attached, thereto engages and moves the arm 118, it will rock the shaft 99 so as to move the knob of the arm 116 from the bell 115, and in the further movement; of the said numbering wheel 103, the pawl 119 being pivoted to the arm 118 will move off of the pin, allowing the arm .16 to fall and cause the knob thereof to en gage with the bell 115; the pin 11]. engaging with the arm 118 acts against the coil spring 119 on the shaft 99 which serves to return the shaft after it has'been moved through the engagement of the pin 111 with the arm 118. Pivoting the pawl 119 on the arm 118, allows the pin 111. of the numbering wheel 108 when the said wheel is returned to its normal position to pass the the pawl which swings out of the way to adapt the said Wheel with its pin to return to its original position. The pin 111 may be attached to the wheel 103 at any desirable point, but I prefer particularly in the machine illustrated, to. attach the pin to the said wheel at'a point where the pin will train.

engage and move the arm 118 to ring the bell 115 after 59 cars have been placed in the train and at a time when the 60th has been added thereto, thus placing the car limit atVGO cars.

The ring or band 17 which has been briefly referred to, forms apart of that mechanism which automatically increases the allowance made to each gross weight of car and contents at predetermined intervals, said allowance to be made depending on the location of said car and contents in a This band 17 has been referred to as being movably supported on a ledge or off set l6 and is provided on the upper face thereof with a scale or chart 120 arranged with a. series of characters, preferably numerals which are the tonnage numbers and represent gross tons of cars and contents. These numbers may be arranged in any suitable manner, and the said scale or chart may be contracted and expanded or not as foration in the disk 8 opposite vto a number corresponding to that called for on the said way-bill or manifest and in rotating the said disk, will through the mechanism described, register on the disk 8, the numbering wheel 26 and disk 32, the pounds of draw-bar pull in the car. It is adapted to move this ring or band 17 to the left at predetermined intervals and to a predetermined distance, said distance varying after the band has been moved a predetermined number of times. The outer edge of the said band is serrated for a portion of its length or provided with'a series of teeth indicated as 121 and engaging with the said teeth is ashort arm 122 slidably carried on a shelf portion 123 of the upper end of an arm 124. The short arm 122 is yieldingly held in engagement with the teeth or serrations 121 of the band 17 by .means of a spring 125, see Fig. 8, which is downwardlydisengages the same from the band, the release of the pointer from the short arm allows spring 125 to return initial-p a H u awlth the serrations :or teeth: ofx-th'e' band, if:

This plate has pivotally connected therewith a pawl 133- adapted to normally engage with the teeth of the disk 129 through and by means of the spring 134 secured at oneend to the said plate and the opposite end bearing against an extension of the said pawl, The plate referred to has an extension to which is pivotally connected the inner-end of an elongated tubular rod 135 into which is telescoped and has move-' ment a rod 136 connected with an arm 137 carried by 'a longitudinally disposed rock shaft or rod 138.- With each complete rotation of the shaft 96 which operates the car numbering wheels 102 and 103 it is intended to reciprocate the" tubular rod 135 for imparting movement to the plate 131. It is understood that when the shaft 96 makes a complete rotation that 10 cars have been placed in a train and it is after the first ten cars have been added'that it is intended to operate the band 17, and move it the distance of-one tooth through and by means of the arm 124 and the devices connected therewith, for the purpose" of changing the position of the band 17 and the tonnage numerals thereon to provide for the increased allowance made to'each gross weight of car and contents added in the second ten cars placed in the train. The movement of the arm 124 is repeated after each complete rotation of the wheel 102 and after each tenth car has been added to the train for the purpose of moving the band 17 the distance of one tooth, until after the 40th car has been placed in the train when it is intended. that the ring or band 17 shall be moved the distance of two teeth after each complete rotation of thewheel 102or the placing of each ten cars thereafter in the train.

If it is desirable the plate 131 may be so constructed that it has a limited movement, which will prevent the arm 12 1 and the ring or band 17 from movin only a given distance, the same would be accomplished either by limiting the disk 129 to a given number of teeth or provide the plate 131 with a slot 148, see Fig, 3, in which operates a pin 149 projecting up from the bearing 132, or if desired both a limited number of teeth and the pin 149 may be employed. It is adapted through the cradle and the rod to release the pawls 133 and 146 from the teeth of the disk 129 whereby the arm 124 may be returned to its normal-position together with the ring or band 17 or upon the release of the pawls as specified from the disk, the operator may release the short arm 122 from the said band 17 and return the arm to the position shown in Fig. 1. This I accomplish by attaching to the rod 66 a depending lever 150 to the lower end of which is pivotally connected a rod or reach 151 provided with the pin 152 adapted to engage with an extended portion of the pawl 1 16 and looping the outer end of said rod or reach at 153 around the rear extension of the pawl 133. Thus, it will be seen that when the operator depresses the cradle 65, in the manner herebefore specified, he will shift the lever150 so as to reciprocate the rod or reach 151 and through the parts 152 and l53'above specified, disengage the pawls 133 and 1 16 from the teeth of the disk 129 to permit free and easy movement to the arm 124;. For the purpose of retain ing the forward end of the cradle 65 in an elevated position to cause the pawls 61 and 84: to engage with the ratchet teeth of the disks 8 and 32 and also to retain the rod or reach 151 in the position shown in Fig. 3, I have provided a coil spring on the rod 66, one end of which engages with the cradle 65 and the opposite end connected with the cross brace 83, see Fig.

Referring to the oft set 51 on the top 2 of the casing, which is best seen in F 1 and 8, the said oil set provides an opening in the top of the casing beneath the same, up through which is inserted the short arm 122 connected with the arm 124 which has attached thereto the disk 129. The inner end of the short arm 122 as was explained is adapted to engage with the serrations or teeth 121 of the ring or band 17 and the outer end thereof overlies and rests upon. the portion 123 of the arm 12 1 which is also projected up through the opening in the casing formed by the ofi set 51, which places the outer end of the short arm 122 outside 1 of the upper edge of the off set 51, whereby an operator is enabled to insert a pointer into the perforation 128 of said short arm for the purpose of releasing the'same, from the ring or band 17 as was described. 4

In addition to the alarm to call to the attention of the operator that his train limit has been reached, it is also provided to rin the said alarm when the disk 32 has rotated into a position to cause thepointer 39'to engage with the oil set or lug 10 on the top 2 of the casing. When the pointen-39 engages the oil" set 40 an engine has been loaded to its full capacity and he is not only advised that such is the case by the sound of the alarm, but the device becomes locked through such engagement of the pointer 39 as specified. The sounding ofthe alarm,

when the pointer 39 engages the off set 40 is accomplished through the plunger 45, see Fig. 9, which is adapted to engage with the upper end of a lever 155 fulcrumed on the part 73 and which has attached thereto a short lever.15($, and said short'lever engages with the lower end of a lever 157 which is pivoted to the upright 25 and provided on its outer end with a knob 158 adapted to hit the bell 115. Disk 32 rotating through the action of the disk 8 andparts described, it

avill be seen operates to raise the knob158 of the lever 157, and when the said lever 157 is released the alarm is sounded by the contact of the knob 158, in the dropping of the lever, all of which it is believed will be understood.

As engines of different weight and dimensions have different tractive power, I provide in the device. an adjustable feature to adjust the draw bar pull on different classes of engines, and as grades and curves vary 1 also provide to compensate for such grades and curves. The means'ior adjusting the draw-bar puli when employing different classes of engines consist of the adjustable finger 17 carried by the plate 18 which is used in connection with the oil set 51 on the top 2 of the casing on which, as

shown in F 1 is provided a scale or chart indicated generally as 159. Said scale or chart 159 is made up of the numerals 10,000-15,000 15,0.00 20,0oo 20,000- eaoco cacao-30,000 aaoooespoo t-35,000 -i0,000, etc. The numerals 10,- O0015,(i0(), provide for the adjustment of the device to an engine rated at anything between 10,000 and 15,000; and likewise the next i'iumerals 15,00020,000 provides for the adjustn'ient of a device rated at anything betwecn1: 3,000 and 20,000, the remainingnumerals being provided for substantially for the same purpose as those just above mentioned and the said numerals as they have been mentioned in their order are placed on the off set above the openings eeaeei or perforations 5,0 in the concave'face of said 011 set. As shown in Fig. 1, the device is 'set for reducing gross tons of cars and con tents to pounds of draw-bar-pull 1n connection with anengine rated at, say, 18,000

adjusting thedevice to engines of different capacity; that is to say, when adjusting the finger 17, as shown in Fig. 1 to ther'ate of 18,000 as was suggested, the plunger 45' of the pointer 39 is inserted into the perfo- II ration or hole 33 which is opposite the numeralor character 18 on the disk This provides for the locking of the device when the pointer 39 engages with the 011" set or lug 10 of the top 2 of the casing indicating 1 that the engine has received its full tonnage nection with the chart or scale 120 and the ring or band17 on which the same is provided, a scale or chart which is indicated as 160, see Fig. 1, suitably attached to the upper face of said ring or band 17. Said scale or chart 160 consists of suitable nu- ,merals and represents pounds of draw-bar pull, for different degrees of curve and grade and the same cooperates with an arrow, or pointer 161 suitably attached to the top 2 of the casing as shown in Fig. 1.

As an example of adjusting the machine to a division of road where the grades and curves vary in opposite directions from a certain point, attention is called to the following: VVewill say that we have a division of road from A to K and trains are made up at stations A, D. and L K. placed at station D to compute the drawbar pull in trains eastbound to A. and westbound to K?, the grade east to A from D is twenty-five feet to the mile, and'no curves, and west to K from D itfis thirtyfeet to the mile and arfour degreecurve. The draw-bar pullin' both directions from: D has been worked out and found to be 16-7 pounds per ton east to A zfrom :D and 20 pounds per ton west to'.-,K- from, D.? The operator will "place a. pointer in theper-foration of the short arm 22 and withdraw the same from engagement. with the serrations or teeth of the band 17 and he will then adjust the We, will assume that a machine is which cooperates with the finger 17 when said band untiljthe t-hegtop "2 of the casing points to sixteen and onehalf on the chart "or scale Q 160.

Now, if in the operation of the machine a pointer is placed in the perforation or hole 9 inthedisk 8 opposite'the numeral .10

j on the ring or band 17 and the disk 8 is moved in the direction, of the arrow indicated on the top plate 18, of Fig. 1, until the said pointer engaged with the finger 47 which is inserted in the perforation 50 of the ofl set 51 which represents the rating of an engine 15,000 to 20,000.? The device through the operation of the said'disk 8 will impart movement to the numbering wheel. 26 and in the manner. hereinbefore specified, and register 165 pounds, the numbers indicating such appearing beneath the opening or slot 6 in the top of the casing. This computation is based on a train which is moving east to ,A from D. If the train is to move west to K from D where the resistance is twenty (20) pounds per ton, the operator will insert the pointer in the perforation of. the short arm 22,. as was previously explained, and Withdrawing the short arm from the ring or band 17 he s will move the band to the left. until the arrow 161 points twenty on the chart or scale 160 and locking the parts in such position. It will thus be seen that the ten (10) ton car will register 200pounds, and cars of their weight in proportion; This mode of adjusting compensates for different grades, curves, and ratings with one and the same machine.

By examining Fig. l'it willbe seen that when the band. 17 is adjusted to 161; pounds per ton, there are 33 holes or perforations of the disk 8 between the fingery17 and the tonnage numeral on the band 17 indieating a car of ten (10) tons; each of said perforations representing five (5) it will be seen that when the said disk Sis moved the distance of .33 holes, whichare multiplied by five the device will. register 165 pounds. Now, when the band 17 is adjusted so that the numeral'20, of the chart 160 is opposite the arrow 161 the distance between the finger i7 and the tonnage numeral 10 has been increased 7. perforations or holes on the disk 8;.thus when it is moved six additionaldistanceof 7 perforations, making forty (40). in all, .that the device will register two; hundred (.200) pounds. I I

An engine with only 10,000 to 15,000 tractive, power, hauls less cars and tonsth an an engine with f 20,000 tow-25,000 pounds or more; hence its train ilength when" fully loaded willbe short. To adjust for. engines of difierent capacity, all that is necessary for the operator' whe handles the. device is to get the engine nnrnbermThe general custom among railroads is to number all machines ofthe same size and capaclty in consecutive order, for example:

The engine number given'to the nian in charge to prepare train, is Number 433'; this being 18,000 pounds, he inserts the pointer into the' perforation in the shoulder as of the finger 47 and adjusts the said finger to the perforation 50 in the off set 51 beneath the numerals 15,000 to 20,000, of the scale or chart 159, substantially as is seen in Fig. 1, this being the rate as shown. This adjustment allowsfive pounds per car more than for engines with 10,000 to 15,000 pounds, and twenty-five pounds per car less than is allowed for engines with FE-5,000 to 40,000 pounds, as was previously explained. The greater the capacity of engines the greater number ofcars will be hauled and the greater number of. cars the greater the resistance per ton, hence the necessity for the adjustment as shown. To make a further allowance to engine when a train is ,composed of an unusual number of light cars, I provide, as was previously described, to automatically increase this allowance five pounds per car for the 10th car; five more pounds per car, making (10) ten after the 20th car, an additional five pounds per car after the 30th car, and ten pounds per car after the 40th. car, making twentyfive pounds more after the lOth car is added to the train. A ten ton car next the engine as shown, registers 65 pounds, the same car it outside the 41st car from the engine will register 190 pounds. It was previously explained that when the 40th car was reached, the band 17 was released the distance of two of its serrations or teeth 121, allowing it to move that distance to the left. This same ten ton car, after the 51st 'car from the engine will register 200 pounds instead of 105. It is understood that ten pounds per car allowance made to the 10th car is also allowed to the 50th, 60th, th, etc. in other words, five additional p unds per car is allowed every ten cars up to the 40th-car, at the 40th, 50th, 60th, 70th and th car, this allowance is doubled and ten pounds per car instead of five is automatically allowed. The mechanism for providing such allowance having been described, and all of which it is believed will be understood.

The spacing or placing of the tonnage numerals on the band as shown in the drawings'represents a very light grade and curvature and will vary as the curves and grades increase, so that on aheavy grade and sharp I t (.6109)? (.6 20, L4 77 or curve the draw-bar pull on a;seventy (70) ton car may increase from 410 to 1500 pounds and to permit of taking car of such variations, I reserve th'eright to change the unit numbers as was suggested from 5 t 20, 77 (4 ,7 d 80 in order to keep the devices down to a very small size and very compact.

In order to permit the same machine to adjust the draw-bar pull of cars over different grades and curves I reserve the right to change thelocation of the numbers representing the tons of cars, by stamping, printing or otherwise attaching them at different locations on the band, but substantially the same numbers as appear or more, will appear in consecutive order on the said band. This may be found necessary by reason of the variation in the bands of drawbar pull per ton of cars over the different degrees of grades and through curves of different degrees. For example, attachan engine to a train of cars of 40 gross tons each on a level tangent and exert its tractive power, which we find to be 30,000 pounds and it moves 50 cars of 40 tons each equal to 2000 pounds, 50 cars divided into 30,000 pounds gives 600 psunds draw-bar pull per pound and 600 pounds divided by 40 tons gives 1.5 pounds per ton resistance due to wheel friction on a 40 gross ton car. This ratio increases per ton of cars of less than 40 gross tons and decreases per ton on cars of more than -10 gross tons. This variation caused by grade and curvature makes it necessary to provide a machine with numbers adjusted on i the band to fit each district according to the grade and curves, or to provide for changing the location of numbers on the same" to adapt it to be moved to the right or left before compilin the draw-bar pull. For example, with a machine located at station D and train move to A east, andwest to K and on the east end the grade is found to be 30 feet and tour de grees curves, and on west end the grade is found to be 28 feet and a four degree curve, a 40 ton car going east to A has 600 pounds of draw-bar pull and the same car going west to K has only 572 pounds or" draw bar pull. ow, in order to malts the same machine compute accurately the drawbar pull on trains moving in each direction, it is arranged that the hand may be set six spaces or the distance of six serrations or teeth, right, instead of to the left, before compiling the draw-bar pull on trains moving west, which then causes the 4.0 ton car to register 30 pounds less on account of the reduced resistance due to reduced grade from 30 to 28 feet to the mile.
